SPECIFICATION forming part of Letters Patent No. 415,065, dated November 12, 1889. Application filed August 3, 1889. Serial No. 319,662 (No model.) i

- ments in display-frames, and has for its objectto provide a frame or stand simple and cheap in construction and capable of ready adjustment in all directions; and to these ends it consists in certain improvements in construction, all as will be hereinafter-pointed out, and the novel features pointed out in the claims at the end of this specification.

In the drawings, Figure 1 is a perspective view of a display-frame constructed in accordance with my invention; Fig. 2, a vertical, and Fig. 3 a cross-sectional view showing the manner of adjusting the telescoping sections. Fig. 4. is a sectional view of one of the brackets supporting one of the pivotal arms; Fig. 5, a perspective view of the parts separated, and Fig. 6 a view of a modification.

Similar figures of reference in the several figures indicate the same parts.

The frame to which my present invention is shown applied preferably consists of two standards 1 1, provided with suitable feet adapted to be secured to the floor or any suit able support, said standards being preferably constructed of metallic tubing, and into these standards are inserted the depending rods or tubes 2 2 of the upper section 3. The upper portion 3 of the frame may consist, as shown, of two sections 4 4, hinged together, and the lower one being hinged to the upper ends of rods 2 2 in any suitable manner,which sections may be connected by suitable rods or tubes 5 5 in the ordinary or any preferred manner. a

As a means for adjusting the upper section of the frame upon the lower one, which, as stated, is of tubing, I provide a hollow bulb or enlargement 6, of spun or cast metal, secured to the upper end of tube 1, and in the side of said tube provide a recess or aperture 7, in which operates a clamping-block 8, curved on the outside to conform to the depending rods 2, and having a broad surface bearing on said rods, so that when moved inby a screw 9, passing through the bulb 6 and abutting against the block, the said rods and the upper portion of the frame will be securely held without danger of crushing the rods if made of tubing. In order to prevent the block moving too far, a pin 10 is passed down through the sides of 'the bulb and through a recess or groove 11 in the face of the clampingmblock, said groove being deep enough to permit the free movement of the block, as will be understood. This form of connection between the upper and lower sections is not only ornamental, but insures the clamping device a broad bearing on the depending rods and can be made cheaply.

Upon the lower sections 1 of the frame are seen red suitable adjustable arms 12, provided with hooks or projectionslS, on which rest rods 14, for holding the goods to be displayed, said arms and rods being hinged and adj ustable, as hereinafter described. "lhe supports for each of the arms 12 preferably consist of collars 15 15, secured to the standards 1 by' suitable set-screws 16, passing through and abutting against the standards. On each of the collars are formed lugs or cars 17 17, between which passes a lug 18 on a bracket 19, said bracket being secured in positionby a pivot-pin 20, passing through the lugs, as shown. The forward portion of'bracket 19 is provided with flanges 21, between whichthe enlarged ends of the arms 12 upon which they are pivoted.

It is desirable that the arms 12 be capable of adjustment to any angle in order to elevate or. depress the rods 14 as may be desired, and as a means for providing for this, and at the same time obviating the necessity of cutting ratchet-teeth on the inside of the flanges or plates 21,1 construct the device as follows: The inner end of each of the arms 12, located between plates 21,-'is reduced or preferably provided with a recess 23 on one side,a central aperture 24, and around the latter a series of perforations or recesses 25. In the recess 23 is arranged a plate or disk 26, having a boss 27, fitting the aperture 24, and a pin or projection 28, beveled on one side, adapted to enter one or the other of the recesses 25, depending on the adjustment of the arm, said disk being normally pressed toward the side of the arm and the pin held in pass and one or the other of the recesses by a spring 29, arranged between it and one of the plates 21. 'A pin 30 passes through the two plates 21, one end beingreduced to pass through the central disk 26 and one plate, while the other or larger end has a bearing in the other plate, the shoulder 31 abutting against the boss on the disk, said pin serving not only as the pivotal point of the arm, but operating when pushed in to release the pin in the disk from the perforations 25. The disk 26 is provided on one side with a recess 32, entered by a sci-cw 33, passing through one of the flanges 21, for the purpose of preventing rotation with the arm 12 on the pivot-pin; and in order that the arm on disk may be withdrawn without removing the screw I preferably make said recess 32 open on one side and form a recess 34 in the end of the arm, so that when the arm 12 is moved to horizontal position with the two recesses in line the pivot-pin may-be withdrawn and the arm removed. The pivot-pin isheld in position and prevented from removal by a screw 35 and washer 36 in its end engaging one of the plates 21, which screw, however, will not prevent its inward movement to release the disk and arm when desired to adjust the latter.

The operation will now be understood. The disk, being prevented from rotary motion on the pin by its securing-screw, forms a lock between the bracket and arm, which may be released by pressing the pin inward against the tension of the spring 29, disengaging the pin on the disk from recesses 25, and after the adjustment is accomplished and the pin released the arm will be securely held. By bevelingthe under side of the pin the arms may be moved upward without pressing the pin,'but they cannot be moved in the opposite direction without releasing them.

While I have described the construction of but a single arm-adjusting device, it will be understood that they are all the same, and

also that the arms between which a rod 14 passes are adjusted simultaneously. However, I do not wishto be confined to two arms between which a rod extends, as single ad justable arms with other devices than pins 13 on them could be employed.

The above-described arm-adj ustin g device is very simple, and the parts can be cheaply made and put together by an unskilled operator, and their release for adjustment is accomplished simply by pushing in the pin.

. In the drawings I have shown the cars 17 17 as rounded on the corners, so that the arms may be turned on their pivots, the connecting-rods preventing independent motion; but it will be understood that if desired to employ a single arm, or for any other reason, these shoulders could be made square, as in Fig. 6, and by engaging with the bracket prevent swinging.

I claim as my invention- 1. In a display-frame the combination, with the tubular standard and the bulb or enlargementthereon, of the clamping-block located within said enlargement, a stop for limiting its inward movement, a screw passing through the bulb and operating to press the block inward, and a rod or tube within the standard and bulb adapted to be clamped by the block, substantially as described.

2. The combination, with the tubular standard, the enlargementon the end thereof, theclamping-block in said enlargement having the groove or recess, the limiting-pin secured to the enlargement and operating in the recess in the block, and the clamping-screw operating in the block, of the tube or rod sliding in the tubular standard and clamped thereto by the clamping-block.

3. The combination, with the tubular standard having the aperture in the side, the hollow bulb thereon, the clamping-block operat ing in the bulb through the aperture in the tube having the recess, the pin for limiting the movement of the clamping-block, and the clamping-screw, of the tube or rod sliding in the standard and adapted to be clamped thereto by the clamping-block, substantially as described.

4. The combination, with the bracket having the plates thereon and the adjustable arm having the series of perforations therein, of the .disk secured to the bracket, having the pin co-operating with perforations, the spring arranged between it and one oflthe plates, and the pivotal pin having a bearing in the plates and operating on the disk to release it, substant-ially as described.

5. lhe combination, with the bracket having the plates andthe adjustable arm having the series of perforations therein, of the disk secured to the bracket, having the boss on which the arm is pivoted, the pin thereon, the spring, and the pivotal pin supported on the bracket on which the disk is supported having the shoulder for operating on the disk, substantially as described.-

6. The combination, with the bracket having the plates thereon, the adj ustablc arm, and the series of perforations therein, of the disk having the pin co-operating with the perforations and the recess in one side, the spring, the pin operating on the disk, and the projection, as a screw, co-operating with the disk to prevent rotation, substantially as described.

7. The combination,with the standard, the collar adj nstably secured thereto, having the perforated lugs, the bracket having the perforated lug co-operatihg with those on the collar, and the pinsecuring them together, of

the adjustable arm pivoted on the bracket.

and locking devices between the bracket and arm for holding the latter in adjusted position, substantially as described.
